Analisa Udara Ambient (H2s, No2, Nh3, So2) di Balai Teknik Kesehatan Lingkungan Pengendalian Penyakit (Btkl Pp) Kelas I Medan

Abstract

Analysis of ambient air (H2S, NO2, NH3, SO2) at Balai Teknik Kesehatan Lingkungan Pengendalian Penyakit (BTKL PP) Class I Medan is to know the pecentage of H2S, NO2, NH3 and SO2 at the air around BTKL PP. The air is pumped into the impinger through absorbent bottle which each contains absorbent solution 10 mL. Make a note of the F1 and F2 air flow and wait until 20 minutes. Then put the liquid into a kuvet to be analyse by spectrophotometry. The result of the analysis of ambient air with SO2 absorbent is 26,58 μg/Nm3 , NO2 absorbent is 0,556 μg/Nm3, H2S absorbent is 13,608 μg/Nm3 and NH3 absorbent is 0,127 μg/Nm3. Which is the requirements of Peraturan Pemerintah Undang-Undang Nomor 23 Tahun 1997 about Air Pollutan Control is declared that the air is safe and fulfill the requirements for human and the environments.
